AFR gauges work with voltages. According to the Pre-Set program and voltage the gauge puts a reading.

Example:

Program 1 : Gasoline, 1.25Volts = 12.5AFR

Program 2 : Methanol, 1.25Volts = 5.52AFR

Let's say we use 100% gasoline OFF boost while shifting to 100% methanol ON boost. If program 1 is selected and the engine is tuned to run 5.52AFR on methanol, the gauge should represent a reading of 12.5AFR.

Methanol likes rich mixtures so if using 100% methanol ON boost the lower the AFR value the better power output. Actually seeing 10AFR using program 1 and 100% methanol is considered safe and powerful.

The only drawback is fuel consumption.
